Description

Technical Field

The present invention relates to cosmetic compositions for topical application comprising colloidal silver and a combination of plant extracts, for use as cosmetics.

Background

There are a number of cosmetic skin conditions which may cause distress to humans.
Said distress may be due to sensations and an unsightly appearance associated with the condition, such as dry skin, reddening of the skin, itchy skin, irritated skin, chapped skin, pigmentation of the skin.
Sufferers presenting with these conditions often wish to alleviate their distress by using some form of remedy for the condition. One option for addressing these conditions may be the use of prescription or over-the-counter pharmaceutical preparations. However, there is a consumer demand for natural remedies, or non-pharmaceutical remedies.
Given that these conditions may affect only a portion of the surface of the body of a sufferer, there is a consumer demand for a local approach of addressing the cosmetic skin condition, rather than a systemic approach. One such suitable approach may be a topical application of a remedy which may reduce or diminish the cosmetic skin condition.
Accordingly, there is a need for compositions suitable for topical application to cosmetic skin conditions which may at least partially alleviate dry skin, reddening of the skin, itchy skin, irritated skin, chapped skin, pigmentation of the skin, as appropriate.

Summary

The invention relates to a cosmetic composition as defined in Claim 1 and dependent Claims.

Detailed Description

In the specification and claims, a volume- to -volume ratio or percentage may be indicated by "(v/v)". A weight to volume ratio or percentage may be indicated by "(w/v)". A weight- to-weight ratio or percentage may be indicated by "(w/w)". Unless otherwise specified, ratios or percentages are given in relation to the weight or volume of the total composition, as appropriate.
The unit "ppm" refers to "parts per million", and may be used herein to indicate a concentration of a material in a fluid phase. Unless otherwise specified, all values given as ppm are given as weight to volume (w/v) percentages. Accordingly, 1 ppm is equivalent to 1 × 10^-4 % (w/v).
The compositions of the present invention are suitable for topical application. That is, the compositions may be applied to body surfaces such as the skin.

Base

The composition consists of a base, or carrier. The base is used as a vehicle for the other components of the composition. For the avoidance of doubt, the term 'base' as used herein does not mean a Brønsted-Lowry base or a Lewis base.
The base is preferably a pharmaceutically acceptable base. The nature of the base may influence the formulation of the composition. For example, a suitable base may comprise water (in particular water purified by distillation, ion exchange, reverse osmosis or any other suitable method), or a mixture of water and C1-C4 alkanol. A composition comprising such a base may suitably provide a topically applicable aqueous suspension formulation. Depending on the ratio of water to C1-C4 alkanol, a topically applicable aqueous suspension may be more suitable for spray application (that is, the suspension is applied to the skin as droplets in an aerosol), or may be more suitable for manual application (that is, the user applies the suspension to the skin with a cloth, pad, or part of their body, for example their hand).
In another example, a suitable base may be an oil, or emulsion of oil and water. In some embodiments, the base may be an ointment base.
Any suitable ointment base may be used. A suitable ointment base may comprise an oleaginous base. Oleaginous bases typically comprise hard paraffin, soft paraffin (also known as petroleum 20 jelly, petrolatum, white petrolatum or multi-hydrocarbon), microcrystalline wax or ceresine. Such bases are typically anhydrous or have a low water content. These bases may further comprise a film forming agents to provide a protective film after application to the skin. Suitable film forming agents include polyvinylpyrollidone, polyvinyl alcohol and cellulose derivatives.
Another suitable ointment base may comprise an absorption base (also known as an emulsion base). Absorption ointment bases typically comprise either an oleaginous base as described above and a water-in-oil surfactant, or a hydrophilic oleaginous base, to allow for the formation of a water-in-oil emulsion upon addition of water. Such bases may comprise any of the oleaginous bases described above and/or components selected from: lanolin, beeswax, cetyl alcohol, stearyl alcohol, cetostearyl alcohol, and sodium lauryl ether sulfate. Examples of appropriate absorption bases include hydrophilic petrolatum, anhydrous lanolin, Aquabase@, Aquaphor@ and Polysorb@.
Another suitable ointment base may comprise a water-in-oil emulsion base. Water-in-oil emulsion bases typically comprise water and any of the ointment base components described above. In particular, water-in-oil emulsion bases typically comprise a water-in-oil surfactant. Examples of appropriate water-in-oil emulsion bases include cold creams, hydrous lanolin, rose water ointment, aqueous cream, Hydrocream@, Eucerin@ and Nivea@.
Another suitable ointment base may comprise an oil-in-water emulsion base. Oil-in-water emulsion bases typically comprise water in an amount greater than that in a water-in-oil emulsion base, and any of the ointment base components described above. In particular, oil-inwater emulsion bases typically comprise an oil-in-water surfactant. Examples of appropriate oil-in-water emulsion bases include hydrophilic ointment, Dermabase@, Velvachol@ and 15 Unibase@.
Another suitable ointment base may comprise a water-miscible ointment base. Water-miscible ointment bases typically comprise a combination of low and high molecular weight polyethylene glycols. Examples of appropriate water-miscible ointment bases include PEG 20 ointment and Polybase@.
A composition comprising such ointment bases as described above may suitably provide a topically applicable ointment formulation, or topically applicable cream formulation.
In another example, a suitable base may be a gel. 'Gel' as used herein refers to any dispersion of inorganic or organic molecules in a liquid system wherein there is at least some cross-linking or association between the inorganic or organic molecules. Gels may be prepared by combining a liquid such as water or aqueous C1-C4 alkanol with suitable gelling agent(s), such as carbomers, carboxymethyl cellulose, ethylcellulose, gelatin, hydroxyethyl cellulose, hydroxypropyl cellulose, magnesium aluminum silicate, methylcellulose, poloxamers, polyvinyl alcohol, sodium alginate, tragacanth, and xanthan gum. A composition comprising such a base may suitably provide a topically applicable gel formulation.
In another example, a suitable base may comprise water and/or C1-C4 alkanol and a propellant. Suitable propellants may include hydrocarbons, hydrofluorocarbons, and compressed gases. A composition comprising such a base may suitably provide a topically applicable aerosol formulation.
The base is present in the composition in an amount of from 80% to 99% (v/v), or 85% to 99.5% (v/v), or from 90% to 99^% (v/v). The base may be present in the composition in an amount less than or equal to 99%(v/v), or 99% (v/v), or 98^%(v/v), or 97^% (v/v), or 96^% (v/v), or 95% (v/v), or 90^% (v/v). The base may be present in the composition in an amount greater than or equal to 80% (v/v), 85% (v/v), 90^% (v/v) ,95% (v/v), 96^% (v/v), 97^%(v/v), 98% (v/v), 99^% (v/v).
In a preferred embodiment, the base comprises water. In a particular embodiment, the base essentially consists of water.

The silver is present in an amount of from 0. 1 ppm to 100 ppm, preferably from 0.5 ppm to 50 ppm, or from 1 ppm to 10 ppm, or from 5 ppm to 10 ppm; that is, from 1 × 10^-5 to 1 × 10^-2 % (w/v), or preferably from 5 × 10^-5 to 5 × 10^-3 % (w/v), or from 1 × 10^-4 to 1 × 10^-3 % (w/v), or from 5 × 10^-4 to 1 × 10^-3 % (w/v). The silver may be present in the composition in an amount less than or equal to 100 ppm, or 50 ppm, or 10 ppm; that is, less than or equal to 1 × 10^-2 % (w/v), or 5 × 10^-3 % (w/v), or 1 × 10^-3 % (w/v).The silver may be present in the composition in an amount greater than or equal to 0.1 ppm, or 0.5 ppm, or 1 ppm; that is, greater than or equal to 1 × 10^-5 % (w/v), or 5 × 10^-5 % (w/v), or 1 × 10^-4 % (w/v). Suitably, the silver may be present in the composition in an amount of approximately 5 ppm; that is, 5 × 10^-4 % (w/v).

Plant extract

Compositions according to the present invention comprise plant extract. A plant extract refers to a substance that has been removed from plant material. Plant extracts may be prepared by treating any plant material with an extractant to extract at least some components of the plant material from the plant material into the extractant. Extractant may be referred to as solvent. The resulting extractant containing at least some components extracted from the plant material is referred to herein as "plant extract". Put another way, "plant extract" may refer to components removed from plant material by treating the plant material with an extractant.
The plant material which is treated with extractant to provide a plant extract may be or derive from any part of a plant, for example, the leaves, bark, roots, seeds or fruits of the plant. In the preparation of plant extract, the plant components extracted from the plant material will be at least partially soluble or suspendable in the extractant. After the plant material has been treated with the extractant, the insoluble plant material may be left in the extractant, or the insoluble plant material may be separated from the extractant. The insoluble plant material may be separated from the extractant according to any appropriate method, for example, decantation, filtration or centrifugation. In preferred embodiments of the present invention, the insoluble plant material has been separated from the extractant; the plant extract does not comprise insoluble components. In a particularly preferred embodiment, the plant extract is prepared by cold percolation extraction. Cold percolation extraction includes placing plant material in a perforated flask or vessel and treating the plant material with cold extractant. The resulting plant extract will pass through the perforation, leaving the insoluble and/or insuspendable plant material in the flask or vessel.
Suitable plant extract extractants include any which may be used to extract components from the plant material; that is, any extractant in which at least some of the components of the plant material are soluble or suspendable. In one embodiment, the extractant may comprise a C1-C4 alkanol. Suitable C1-C4 alkanols include methanol, ethanol, n-propanol, isopropanol, nbutanol, isobutanol, sec-butanol, and tert-butanol. In one embodiment, the extractant may comprise methanol and/or ethanol. In a particular embodiment, the extractant may comprise ethanol.
In another embodiment, the extractant may comprise acetic acid, glycerine (in particular vegetable glycerine), propylene glycol, honey, or water. Plant extracts may be prepared with hot water or cold water.
The extractant may comprise a combination of extractants. For example, the extractant may comprise a combination of any of the extractants given above. In a particular embodiment, the extractant may comprise water and a C1-C4 alkanol. Such a combination may be referred to as an aqueous C1-C4 alkanol. In a preferred embodiment, the extractant comprises water and ethanol. Such a combination may be referred to as aqueous ethanol.
In a further embodiment, the extractant may essentially consist of any one of the extractants given above, or a combination thereof. In a particular embodiment, the extractant may consist of water and a C1-C4 alkanol. In a preferred embodiment, the extractant consists of water and ethanol.
Aqueous ethanol may have any appropriate ethanol content. For example, the aqueous ethanol may have an ethanol content of from 5% to 95% (v/v), 10% to 90^% (v/v), 20% to 80^% (v/v), 30% to 70^% (v/v), or 40% to 60^% (v/v). The aqueous ethanol may have an ethanol content of greater than or equal to 5% (v/v), 10^% (v/v), 20^%(v/v), 30^% (v/v), 40^% (v/v), 50^% (v/v), 60^% (v/v), 70% (v/v), 80% (v/v), 90% (v/v), or 95% (v/v). The aqueous ethanol may have an ethanol content of less than or equal to 95% (v/v), 90^% (v/v), 80^% (v/v), 70^% (v/v), 60^% (v/v), 50^%(v/v), 40^% (v/v), 30^% (v/v), 20^% (v/v), 10^% (v/v), or 5% (v/v).
The plant extracts suitable for use in the present invention may be prepared by treating plant material with extractant in any appropriate ratio. For example, plant extracts for use in the present invention may be prepared by treating plant material with extractant in a ratio of from 1:1 to 1:12 (w/v) plant material to extractant.
Plant extracts suitable for use in the present invention may be referred to by a variety of names. Plant extracts suitable for use in the present invention particularly include products which may commercially be referred to as extracts (typically an aqueous ethanol extraction of plant material carried out in a ratio of approximately 1 : 1 (w/v) plant material to extractant), tinctures (typically an aqueous ethanol extraction of plant material carried out in a ratio of approximately 1:3 to 1:5 (w/v) plant material to extractant), mother tinctures (typically an aqueous ethanol extraction of plant material carried out in a ratio of approximately 1:9 (w/v) plant material to extractant), and tisanes such as infusions (typically a hot water extraction of plant material), decoctions (typically an aqueous extraction of plant material carried out in boiling water over an extended period of time) and macerations (typically an extraction of chopped plant material in cold water).
Plant extracts suitable for use with the present invention may be purchased from the vendor G Baldwin & Co.
In some embodiments, the plant extract is an extractant-free extract. That is, a plant extract has been prepared according to the above methods, and then the extractant has been removed to leave a dry substance. The dry substance may correspond to the plant components extracted from the plant material or derivatives thereof only.

Description of examples and embodiments with reference to the Figures.

Figure 1 shows a subject 100 with an area of unbroken skin 110. A localised area of skin 120 presents with an open wound 122. This picture of subject 100 was taken at 15:00 on Day 0 of a test period, prior to application of any composition described herein.
A composition consisting of aqueous extracts of Equisetum arvense, Symphytum officinale, Echinacea purpurea, Stellaria media, Aloe vera, Matricaria recutita, Hypericum perforatum, Calendula officinalis, and Panax ginseng in a ratio of 3:4:3:2:3:2:2:4:4 (w/w) in 5 ppm aqueous colloidal silver was prepared (corresponding to Example 33). The area of skin 120 containing the wound was selected, and the composition topically applied to the selected area. Said composition was regularly applied to the area 120 through a test period of 8 days.
Figure 2 is a picture of subject 100 taken at 10:22 on Day 3 of the test period. The open wound 102 in area 120 has scabbed to provide a scabbed wound 124.
Figure 3 is a picture of the subject 100 taken at 16:26 on Day 6 of the test period, showing a decrease in the size of scabbed wound 124 in area 120 to provide scabbed wound 126.
Figure 4 is a picture of the subject 100 representing the appearance of Subject 100 on Day 8 of the test period. Scabbed wound 124 in area 120 has healed completely to provide new skin 128. New skin 128 in the area of skin 120 on Day 8 resembles the unbroken 110. Thus, Figures 1 to 4 demonstrate that regular application of a composition as described herein to an open wound may result in an increased rate of healing of the wound.
In one embodiment, a subject 200 presented with a nevi (mole) in a localised area of skin 220. The nevi was roughly circular in shape, had a darker pigmentation compared with the surrounding normal skin tone and protruded from the surface of the skin. A composition consisting of aqueous extracts of Chelidonium majus, Thuja occidentalis, Mahonia aquifolium, Aloe vera, Matricaria recutita, and Calendula officinalis in a ratio of 2:4:1:1 :1:4 (w/w) in 5 ppm aqueous colloidal silver was prepared (corresponding to Example 36). The area of skin 220 containing the nevi was selected, and the composition topically applied to the selected area. Said composition was regularly applied to the selected area through a test period of 95 days.
Figure 5 is a picture of subject 200 taken on Day 80 of the test period. Subject 200 has an area of normal skin tone 210. The localised area of the skin 220 presents with a portion of darker pigmentation 222 compared to the normal skin tone 210. The darker pigmentation 222 also protrudes from the surrounding normal skin 210. The size of the nevi, the pigmentation of the area 220, and the protrusion of the nevi from the skin are reduced compared with the appearance of the nevi prior to application of the composition. In particular, localised area of skin 220 now contains normal skin tone 212, whereas on Day 0 this area was part of the nevi.
Figure 6 is a picture representing the appearance of Subject 200 on Day 95 of the test period. The pigmentation of the skin 222 has substantially decreased; the pigmentation of the skin 222 in the area of the body 220 now resembles the normal skin tone 210, and area of skin 220 now contains only skin of normal skin tone 214. Further, there is now no protrusion from the body. Thus, Figures 5 and 6 demonstrate that regular application of a composition of the present invention to a nevi may result in a reduction 10 in the pigmentation and physical protrusion of the nevi.
Figure 7 shows a subject 300 with a normal skin tone 310. Localised areas of skin 320 and 330 present with recently inflicted mosquito bites, resulting in reddened and raised skin 322 and 332. This picture of subject 300 was taken prior to topical application of the composition described herein.
A composition consisting of aqueous extracts of Arctium lappa, Urtica dioica, Echinacea purpurea, Stellaria media, Matricaria recutita, Hypericum perforatum, and Calendula officinalis, in a ratio of 3:4:4:3:2:3:3 (w/w) in 5 ppm aqueous colloidal silver was prepared (corresponding to Example 37). The areas of skin 320 and 330 presenting with insect bites were selected, and the composition topically applied to the selected areas. Said composition was regularly applied (three times-daily) to the areas 320 and 330 through a test period of 24 hours.
Figure 8 is a picture of the subject 300 taken after 6 hours of the test period. Reddened and raised skin 324 and 334 is decreased in size compared with reddened and raised skin 322 and 332. Reddened and raised skin 324 and 334 is of a skin tone more similar to normal skin tone 310 than reddened and raised skin 322 and 332.
Figure 9 is a picture of the subject 300 taken after 24 hours of the test period. Reddened and raised skin 326 and 336 is yet further decreased in size compared with reddened and raised skin 324 and 334. Reddened and raised skin 326 and 336 is of a skin tone even more similar to normal skin tone 310 than reddened and raised skin 324 and 334. Subject 300 also reported a perceived reduction in the itching sensation provided by the mosquito bite after application of the composition.
Thus, Figures 7 to 9 demonstrate that regular application of a composition as described herein to an insect bite, in particular a mosquito bite, may result in a reduction in the size, reddening and itchiness of an insect bite.
Figure 10 shows a subject 400 with unbroken skin 410. Localised area of skin 420 contains a recently inflicted open wound. Localised area of skin 420 contains two smaller areas 430 and 440. Area 430 contains a portion of open wound 432; area 440 contains a portion of scabbed wound 442. This picture of subject 400 was taken at 09:30 on Day 0 of a test period prior to topical application of any composition described herein.
A composition consisting of aqueous extracts of Equisetum arvense, Symphytum officinale, Echinacea purpurea, Stellaria media, Aloe vera, Matricaria recutita, Hypericum perforatum, Calendula officinalis, and Panax ginseng in a ratio of 3:4:3:2:3:2:2:4:4 (w/w) in 5 ppm aqueous colloidal silver was prepared (corresponding to Example 33). The area of skin 420 containing the wound was selected, and the composition topically applied to the selected area. Said composition was regularly applied to the areas 420 for the first 5 days of a test period of 10 days.
Figure 11 is a picture of the subject 400 taken at 10: 12 on Day 3 of the test period. The portion of open wound 432 in area 430 has scabbed to provide portion of scabbed wound 434 in area 430. The portion of scabbed wound 442 in area 440 has reduced in size to provide portion of scabbed wound 444 in area 440. The reddening surrounding portions of wound 434 and 444 in area 420 is reduced compared with that shown in Figure 10.
Figure 12 is a picture representing the appearance of Subject 400 at 11:17 on Day 10 of the test period. The portion of scabbed wound 434 in area 430 has healed to provide new skin 436 in area 430. The portion of scabbed wound 444 in area 440 has healed to provide new skin 446 in area 440. A wound of this magnitude inflicted on subject 400 would not usually be expected to heal within 10 days. Thus, Figures 10 to 12 demonstrate that regular application of a composition as described herein to a wound may result in an increased rate of healing of the wound.
